以元胞自动机模型为基础,将连续的运动离散化,根据实际中车辆在转盘中变速与换道、进出等交通规则制定了环形多道模拟算法.此外,通过增加车辆尺寸参数,比较准确的模拟了混合车流在单/多车道转盘中的运动.对任意一个转盘,模拟算法可以模拟出转盘的交通流,并得到车辆的平均延误时间,从而判断是否实现了对转盘的最优控制. Based on the cellular automaton model, the continuous motion is discretized, and a ring-shaped multi-channel simulation algorithm is developed according to the traffic rules such as speed changing, lane changing and entering and exiting in the carousel.In addition, the vehicle size parameters are more accurate Simulates the movement of a hybrid car flow in a single / multi-lane turntable.For any carousel, the simulation algorithm can simulate the traffic flow of the carousel and obtain the average delay time of the car to determine whether the optimal control of the carousel is achieved.
